ROTARY BRUSH.

Application filed September 17, 1918.

To all whom it may concern Be it known that I RUDOLF R. RADINSE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Rotary Brushes, of which the following is a specification.

This invention relates to rotarybrushes of that type in which a plurality of sets or tufts of bristles or the like are secured to a disk which is mounted on the arbor of the brush.

The object of the present invention is to provide improved means for fastening the. tufts to the disks, without the use of any clamping ring'or separate devices, the fastening means being integral with thedisk itself.

The invention is illustrated in the accompanying drawing in which:

Figure 1 is a side view of the brush.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Referringspecifically to the drawings, (5 indicates a circular disk of sheet metal or the like. From the body of this disk, near the outer edge thereof, a plurality of rows of loops 7 are struck up by slitting the disk. In the drawings, I have shown two rows struck up respectively on opposite sides of the disk. The loops are arranged in circular rows with each loop at a tangent. The tufts or bristles are indicated at 8, and they are folded or bent at the middle as shown at 9 so that the opposite ends project out\\"ardly or radially, and the bends or bights of the tufts are inclosed and held under the loops 7 respectively.

In assembling the parts, the loops are first Specification of Letters Patent.

struck up, and the bights of the tufts are inserted therein, resting against the side of the disk. Then the loops are pressed or swaged down at the middle, as indicated at 10, thereby gripping or clamping the bight of each tuft and effectively holding the tufts on the disks.

The tufts can be quite. :asily renewed by inserting a tool under the loop and bending the same up, permitting the old tufts to be removed and new tufts inserted.

The construction is much simpler and cheaper than those rotary brushes employing a plurality of disks or rings between which the tufts are clamped. 11 is a hole at the center of the disk to receive the arbor, not shown.

I claim:

1. A rotary brush comprising a disk. loops struck up therefrom, and tufts under the loops, said loops being pressed upon the tufts to hold the same.

2. A rotary brush comprising a disk, loops struck up therefrom, and tufts bent to form bights inserted under the loops, said loops being pressed upon the bights to hold the tufts to the disk.

3. A rotary brush comprising a disk hav ing loops struck up on opposite sides thereof, and tufts inserted under the loops against opposite sides of the disk, the loops being pressed down upon the tufts to clamp the same to the disk.

In testimony whereof, I do allix my signature in presence of two witnesses.
